The volume of a cone is equal to (pi*r^2*h)/3
(pi*25*2)/3= 52.35987...
Density = mass/volume
d= 6 grams/ 52.35987 cm^3= 0.11459...
Final answer: D
Your answer is D
because the line plot runs through the point that is 0 to the right and is 2 up
Cos9x - cos5x = -2sin2x.sin7x
sin17x - sin3x = 2sin7x.cos10x
so f(x) =
=
Enrolement increased by 30% that means last year=100%
incease of 30%=30+100=130% now
now=182
percent means parts out of 100 so
130%=130/100=13/10
182=13/10 of x (x represents the number last year)
of means multipy so
182=13/10 times x
multiply both sides by 10/13 to clear fraction
182 times 10/13=x=140
140 students last year
